At Air Quest Heating & Cooling Corp. we understand that you may have a few questions when it comes to your heating and coolings needs. Since 1996, we have helped answer our customer's questions and concerns and have come up with a list of frequently asked questions.

And, as with anything, times change and so does technology. In an effort to keep you up-to-date on industry advancements and trends, we have also included new information that we think you should know about.


How often should I change my air filter?

Check your air filter once a month and change it at least every 3 months. A clean filter will prevent dust and dirt from buiding up in an air conditioning and heating system. A dirty filter slows air flow, making your system work harder. It can also cause your system to stop working.

Replacing your air filter is an affordable way to save energy and keep your system running efficiently.


Why is it important that my condensate drain is checked and inspected?

If plugged, the drain can cause water damage in the house, affect indoor humidity levels, and breed bacteria and mold. When our technicians service your air conditioner or heat pump, the condensate drain is checked and cleared, if necessary, in order to avoid any of these potential problems.

What is Energy Star?

Energy Star is a program that was created by the U.S. Environmental Protection Agency (EPA) to help businesses and individuals make energy efficient purchases. This program places the ENERGY STAR label, a small blue and white logo, on items that meet superior energy efficiency standards. This label provides an easy way for consumers to identify quality, high-efficiency products.

Air Quest Heating & Cooling, Corp. can guide you in finding an energy efficient solution for your home or business. If you are considering updating your system with new, ENERGY STAR rated equipment, call 520-623-1400 for a free estimate.

Why should I consider using a programmable thermostat?

Did you know that properly using a programmable thermostat in your home is one of the easiest ways you can save energy and money? A programmable thermostat helps make it easy for you to save by offering pre-programmed settings to regulate your home's temperature in both summer and winter, even when you are asleep or away.

Oh, and if your programmable thermostat runs on batteries, don't forget to change the batteries each year. Some units will indicate when batteries need to be changed.

What is Freon R-22?

R-22 is the common name for hydro-chlorofluorocarbon (HCFC). R-22 has been used as a refrigerant by HVAC manufacturers for over 40 years, but studies in the past decade have shown that HCFCs contain chlorine, an ozone-depleting agent. For this reason, the United States Clean Air Act set a target date for January 1, 2010 on which HVAC manufacturers must cease the production of products that use R-22.

What is R-410A?

R-410A is the common name for an emerging hydro-fluorocarbon (HFC) that is being used as a refrigerant in the HVAC industry. R-410A is more environmentally friendly than R-22 and is being seen as the most likely replacement for R-22 by HVAC manufacturers. As of the beginning of 2010, the use of alternate refrigerant is required in HVAC manufacturing.

Why are rating numbers important?

Rating numbers indicate the efficiency of heating and air conditioning equipment and are directly related to the amount of energy a specific model uses. The higher the rating, the more efficient the product and the lower your energy bills can be. The federal government establishes rating guidelines and sets minimum efficiency levels. For cooling, the rating is SEER (Seasonal Energy Efficiency Ratio). For heat pumps, the rating is HSPF (Heating Seasonal Performance Factor). Gas furnaces are rated with AFUE (Annual Fuel Utilization Efficiency).

What's the difference between a manufacturer's limited warranty and an extended warranty?

A manufacturer's limited warranty is the warranty that a product leaves the factory with. Typically, it covers specific parts for a limited period of time. Details on limited warranty coverage can be found in your system's Owners Manual.

Extended warranties are optional and are generally purchased at the same time as the equipment. Optional extended warranties cover all parts and may even include labor. There are a variety of optional extended warranties to choose from, but all are designed to offer long-term peace of mind.
